小编too*_*les的帖子

我正在考虑在网站启动阶段使用以下代码向用户显示维护页面,同时向我展示网站的其余部分.

有没有办法向搜索引擎显示正确的302重定向状态,还是应该寻找另一种.htaccess基础方法？

$visitor = $_SERVER['REMOTE_ADDR'];
if (preg_match("/192.168.0.1/",$visitor)) {
    header('Location: http://www.yoursite.com/thank-you.html');
} else {
    header('Location: http://www.yoursite.com/home-page.html');
};

我在一个网站上工作,在XSL中有一些if /或语句,并且对我不确定如何完成的语言有点不了解:

如果[符合一个条件]或[条件二符合],那么[行动]否则做[替代行动]

谁能提供一些例子？

提前致谢!

所以我被迫在一个我正在开发的网站上使用@ font-face,并且不得不说与Google字体相比,我对交叉浏览器渲染质量印象深刻,但它似乎确实对http请求与Cufon相比,因为每个字体需要四个变体用于正文复制,有时需要一对标题.

我一直与cufon合作,因为我发现它是灵活,可靠的跨浏览器和移动,并且尽管偶尔有一些奇怪的空白问题,但易于使用.我对谷歌字体做的不多,因为在某些浏览器中渲染很糟糕.

显然技术已经发展了!这三者有何不同,三者中是否有任何严重的缺陷？

有没有办法从html页面链接到iPhone地图应用程序中的路线？

我们正在添加一个iPhone应用程序,该应用程序将链接到我们网站上的移动页面 - 我们想添加一个方向链接,到目前为止谷歌搜索一直没有发现.

我正在使用YQL调用以下URL

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22UTG.L%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=cbfunc

这将在JSON中返回以下内容

但我正在努力使用这些数据(我是jQuery和JSON的新手)

$.getJSON("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22UTG.L%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=cbfunc",
    function(data){

从这个例子只是闪烁受限的URL错误.

任何人的帮助 - 我只是解析数据并打印到屏幕.提前致谢!

我正在使用以下代码将流量重定向到特定页面(此流量通过谷歌来自旧网站,以前使用我的服务器ip)

RewriteRule ^viewtopic.php?/?$ http://www.myurl.org.uk/ [L,R=301]

据我了解,这^viewtopic.php?/?$应该删除查询字符串,但它不起作用.任何帮助赞赏.

示例URL

http://www.myurl.org.uk/viewtopic.php?f=3&t=44207&start=2265

重定向时的输出

http://www.myurl.org.uk/?f=3&t=44207&start=2265

有人能指出我在谷歌网络工具包中工作的UI设计师的有用指南吗？

我最近开始在一个非常大的高流量网站上工作.我们非常希望减少样式表的大小和数量,缩小是我们要追求的一条路线但是有谁知道检查ID和类使用的任何工具？直接扫描网站,看看什么是活跃的,什么不是？

或者,任何用于编辑css以减少重复和大小的软件？

我正在从无 Cookie 的域为我的网站提供资源。由于跨站点原因，此功能在 Chrome 和 Firefox 中被阻止

Redirect at origin \'http://static.domain.com\' has been blocked from loading by Cross-Origin Resource Sharing policy: No \'Access-Control-Allow-Origin\' header is present on the requested resource. Origin \'http://www.domain.com\' is therefore not allowed access.\n

因此，我将以下内容添加到 htaccess 文件中以启用 CORS

<IfModule mod_setenvif.c>\n  <IfModule mod_headers.c>\n    # mod_headers, y u no match by Content-Type?!\n    <FilesMatch "\\.(gif|png|jpe?g|svg|svgz|ico|webp)$">\n      SetEnvIf Origin ":" IS_CORS\n      Header set Access-Control-Allow-Origin "*" env=IS_CORS\n    </FilesMatch>\n  </IfModule>\n</IfModule>\n\n<IfModule mod_headers.c>\n  <FilesMatch "\\.(ttf|ttc|otf|eot|woff|woff2|font.css|css|js|svg)$\xe2\x80\x9d>\n    Header set Access-Control-Allow-Origin \xe2\x80\x9c*\xe2\x80\x9d\n  </FilesMatch>\n</IfModule>\n

由于某种原因，这不能正常工作 - …

我正在审查海外开发商为我们制作的一些HTML.他们在他们的外部脚本加载标签中使用注释 - 据我所知这只对非常旧的javascript不知情的浏览器有用,他们曾经将脚本呈现为文本 - 这有什么现代的目的还是现在完全冗余？

<script type="text/javascript" src="path/to/file.js"><!--//--></script>  

提前致谢

//在下面的评论之后进行更新:事实证明,评论是在内容管理系统中将问题呈现为标记的问题

<script type="text/javascript" src="path/to/" />

没有评论存在 - 所以答案是他们不再在一般的Web开发中有任何用处,但是在某些特定情况下它们可能有用.感谢Caspar Kleijne指出这一点.
